Summary	This Chinese standard specifies the type B RCD technical requirements and test methods this standard specifies the technical requirements and test methods is a Type A residual current device technical requirements supplement. B-type and B-type RCCB RCBO at 1000Hz and below sinusoidal AC residual currents and pulsating DC residual current three-phase power supply smooth DC residual currents can provide protection. This standard B -type and B-type RCCB RCBO can not be used in DC power systems. Others are not, or GB 16917. 1 GB 16916. 1 residual current occasions covering the technical requirements and test methods under consideration. Or for the manufacturer's declaration of conformity verification
